Interestingly I've had far, far less issues in Arch over a year or so of using it, than I did trying to use Debian stable ~10 years ago.

It could be that I'm just more of a unix beast now and so do it automatically without thinking. I remember having to edit Xorg configuration files, having tons of unsupported hardware, etc.

Arch has basically just worked for me on all my machines with the exception of some esoteric features (e.g. zfs requires a bit of fiddling).

What problems have you had in particular?
